The valve i'sindicated generally at and its rear end is preferably screwed upon the outer end of a relatively short horizontally disposed pipe 11 connected with a liquid supply reservoir 12 supported by any suitable means not shown.

By providing the valve with laterally extending-openings 82 its operation is made easier and smoother.

The present device is one which is simple in construction, convenient to operate and which will effectively discharge a predetermined quantity of liquid downwardly into the hand at each return stroke of the valve. It is easy to keep in repair and the parts are readily accessible requiring only the removal of the cap 17 I claim as my invention:

1. A liquid dispensing apparatus comprising a casing having inner and outer spaced valve chambers of equal bore and an intermediate chamber therebetween of greater cross-sectional area than either of said valve chambers, a valve normally closing the outer chamber and being movable through the intermedi ate chamber to close the inner chamber, said valve being so constructed that subsequent to entering the inner chamber it will permit the latter to remain in communication With the intermediate chamber for a predetermined period during inward movement of the valve, and means for returning said valve 'to normalposition.

2. A liquid dispensing apparatus comprising a casing having inner and outer spaced chambers and an intermediate chamber therebetween of larger cross-sectional area than said outer chamber, a single valve normally closing said outer chamber and movable through the intermediate chamber into the inner chamber and being constructed to gradually cut oil communication between the latter and the intermediate chamber-when moving from the outer chamber, and means for returning said valve to normal position.

3. In a liquid dispensing apparatus in combination, a reservoir, a horizontally disposed casing connected therewith and having a bore forming inner and outer spaced chambers and a liquid receiving chamber'interposed therebetween of a larger cross sectional area than either of said spaced chambers, said receiving chamber and said inner chamber being normally in communication with the reservoir, a single valve corresponding in diameter to said bore and nor-- mally disposed, in the outer chamber said outer chamber having a downwardly eXtending discharge passage, means for moving the valve through the liquid receiving chamberinto the inner chamber to cut off communication between the receiving chamber and'the reservoir and to place the other chamber in communication with the receiving'chamber and means within the casing for automatically returning the valve to the outerchamber when released.
